Title:
  linux treats first partition on sdcard as much bigger than it really
  is?

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  For some reason Linux (dd/mkfs.vfat/mkfs.ext4) treats the first
  partition of my sdcard as 16GB regardless of what fdisk says it should
  be. dd sees the other partitions as the correct size.

  Also if I run mkfs.vfat on the first partition it is treated as a fuse
  filesystem when mounted, it seems very strange. The whole card has
  been zeroed out so it shouldn't be an issue of some other weird data
  on the card. Pulling and reinserting the card after partitioning makes
  no difference. I have also included the fdisk bootsector dump at the
  end of this message.
